NEEEEEEDDDDD HELP ASAPJason wants to compare the mean height of the players on his favorite hockey and volleyball teams. He creates the dot plots shown below: First dot plot is labeled Height of Hockey Players and shows 1 cross on 67, 1 cross on 69, 2 crosses on 70, 2 crosses on 71, 4 crosses on 72, 5 crosses on 73, 3 crosses on 74, 2 crosses on 76, and 1 cross on 78. Second dot plot is labeled Height of Volleyball Players and shows 1 cross on 73, 1 cross on 75, 1 cross on 76, 2 crosses on 78, 2 crosses on 79, 2 crosses on 80, 2 crosses on 81, 2 crosses on 82, and 3 crosses on 84 The mean absolute deviation is 1.83 inches for the hockey team and 2.53 inches for the volleyball team. Which of the following conclusions can be drawn from the data? There is more variability in hockey team member heights. There is more variability in volleyball team member heights. The hockey players are all taller than the volleyball players. The volleyball players are all taller than the hockey players.
Question
Answer:
The correct answer is that there is more variability in the heights of the volleyball team members. The mean absolute deviation shows us how spread out the data is, so the larger the mean absolute deviation the higher the variability.
Both teams have players that are 76 inches tall, so the last two statements cannot be true.
